Widely used dental sealants and tooth repair resins contain substances that degrade into the controversial chemical BPA, but dentists can use the product safely in kids if they make sure to wipe or rinse away residue after treatment, a new study concludes. Pregnant women, however, might do better to wait until after delivery.
The benefits of sealants in preventing kids’ cavities outweighed risks associated with bisphenol A, or BPA, the chemical linked to a host of health ills and banned by many plastic bottle manufacturers, researchers find in the report published in the latest issue of the journal Pediatrics.
“People shouldn’t be scared by this,” said Dr. Burton Edelstein, chairman of social and behavioral sciences at the Columbia University College of Dental Medicine and a co-author on the study. “The amount of exposure is extremely low. And the layer that contains BPA can be wiped off with cotton or rinsed off with a stream of water that can then be suctioned away by the dental assistant.”
